KHB 300

Fully automatic sharpening machine for complete machining of the hook and side angles of carbide-tipped circular saw blades [with integrated measuring system and preparation for robotization]

The KHB 300 is an advanced sharpening machine for carbide-tipped circular saw blades, equipped with a standard integrated probe. This probe automatically records all relevant parameters such as cutting width, blade thickness, and rake angle, ensuring precise machining and high accuracy. Another highlight of the KHB 300 is the automatic determination of the tool zero point by touching the grinding wheel to the saw tooth. This feature ensures precise positioning and reduces sources of error, enhancing the efficiency and quality of the sharpening process. Additionally, the KHB 300 is prepared for the integration of an ABB industrial robot. This enables automated production, increases efficiency, and reduces manual labor. The KHB 300 provides companies with a future-proof, precise, and efficient solution for sharpening circular saw blades and is ideal for fully automated production.

Highlights

  • The space-saving machine concept allows for excellent operability.
  • Easy access for maintenance work on the control cabinet, coolant pump, pneumatics, and fire suppression system.
  • Fast and secure programming and adjustment of circular saw parameters.
  • "LINUX Debian 10" control with multicore processor for high computational power and efficiency.
  • Each tooth geometry, including bevel and rake angles, is ground in a single setting.
  • Repair tooth detection via probe for precise fault detection.
  • Measurement protocol for cutting angle, clearance angle, rake angle, and overhangs to ensure quality control.
  • After the grinding process, run-out at the circumference is measured and logged to ensure maximum precision.
  • All axes are equipped with high-strength roller linear guides for long lifespan and durability.
  • Preparation for the integration of a fully automated loading system (robot) for complete automation.
